边叶

Sepals without or with a very narrow hyaline margin; stems erect to spreading but not frondose, not or scarcely ancipitous (2-edged) when young

没有有一很狭窄透明的边缘的或的萼片；但不是具叶的茎直立到开展，不或几乎不ancipitous(2镶边)幼时 30

By means of the Fourier series expansion, an approximate analytical propagation equation of flattened Gaussian beams passing through an apertured paraxial ABCD optical system is derived, and illustrated with numerical examples, when the transmissivity of the aperture is T = cos.

用傅立叶级数展开法研究了平顶高斯光束通过有光阑限制的近轴ABCD光学系统的传输特性，导出了光阑透射率为T=cos时的近似解析传输公式，硬边光阑的情况可作为Ω=0的特例得到。

Leaf margin with 5-7 lobes on each side ending in 10-30 awns; blade glabrous or barbate; bracts of cupule glabrous; nuts mature 1 year after flowering

叶缘具5-7裂片在每边结束于10-30芒；叶片无毛的或具髯毛；壳斗的苞片无毛；坚果成熟的1 年花后 11 Q。 palustris 沼生栎

Leaves glabrous or rapidly glabrescent, or ciliolate only at apex and margin.

叶无毛或很快脱落无毛，或者只在先端和给镶边。

All those three plants showed the trend of demethylation in DMA treatment, and this ability was strongest in P.

三种植物对DMA都具有一定的去甲基化能力，其中大叶井口边草的去甲基化能力最强。

Leaves basal, opposite; petiole 5-10 X 4-10 mm; leaf blade ovate to orbicular-ovate, 5-8 X 4-7 cm, papery, densely appressed puberulent and appressed pilose (hairs to 1 mm and to 3 mm), eglandular, base broadly cuneate, margin subentire to repand-crenate, apex acute to rounded; lateral veins ca.

叶基生，对生；叶柄5-10 X 4-10毫米；卵形叶片卵形到圆形， 5-8 X 4-7厘米，纸质，浓密贴伏被微柔毛和贴伏的具柔毛的(对1毫米和对3毫米的毛)，无腺体，基部宽楔形，侧脉约4在中脉每边各，不明显。

Leaves semiterete or triangular in cross section, fistulose at least basally; base of inner filaments entire or occasionally 1-toothed on each side.

叶半圆柱形或三角形在横断面上，至少基部中空；内轮花丝全缘的或偶有1齿在每边的基部。

Leaves 3--5-angled in cross section, fistulose; scape lateral; base of inner filaments 1-toothed on each side

叶3 --具5个角在横断面上，中空；花葶侧生内轮花丝1齿在每边的基部 108 ALLIUM chinense 头

Leaves fistulose, margin smooth.

叶中空，光滑给镶边。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
